Inventory Management Hotkeys
This game could really use some hot keys for inventory management, ie shift-left click splits stack in half. Also it would be nice to have a transfer all button in storage containers to transfer all from storage crate to backpack or all from stockpile to cart. Double click transfers stack to backpack. Most games that deal with inventories have this already so there are a lot methods that you can draw from for specific ideas.
Oh god yes. Transfer all button and double click to move between backpack and first open storage slot would be amazing.
